i want to control a motor from my computer using vb, anybody know how? i would also like to recive inputs i.e limit switches so i know when too turn the motor off. so inputs as well as outputs
i'm stuck here guys any got any ideas
also anybody know how to control a joystick port in vb
I was doing some project with stepermotors. I used LPT and direct acces.
INP(portid) ' returns a byte read from the I/O port portid
OUT portid, value ' writes the byte value to the I/O port portid
portid can be any unsigned integer in the range 0-65535. value is in the range 0-255.
pdata = &H378
status = &H379
control = &H37A
OUT pdata, bits ' output data
bits = INP(status) ' input data
What sort of link have you got between your PC and the motor?
i don't have the link yet i want to know the best way too do it
I can help, but first tell me the operating system you are using.
The best thing would be to get a "data I/O" card from someone like "Advantec". That will give you your inputs and outputs for controlling you motor..

:D
I'm using win 2k, the thing 'bout the I/O card could you access that through VB
You do not need an I/O card unless the parallel port is not powerful enough for you. You would have to build some external circuitry to protect your parallel port and have an external power supply, but that's a lot cheaper than any digital I/O card available, and I'm not even sure those cards can source much current.
